Introduction
Science fiction movies have the power to transport us to incredible new worlds, introduce us to fascinating characters, and explore mind-bending concepts. However, not all sci-fi films are created equal. Some are so hilariously bad that they become notorious for their cringe-worthy special effects, absurd plots, and laughable acting. In this article, we’ll count down the top 10 worst sci-fi movies of all time, ranked from bad to worst. Get ready to cringe, laugh, and marvel at these cinematic disasters!
10. Battlefield Earth
Overview
Based on the novel by L. Ron Hubbard, Battlefield Earth is a 2000 sci-fi disaster starring John Travolta. Set in the year 3000, the movie follows a group of humans fighting against their alien overlords, the Psychlos. Despite its big budget and star power, Battlefield Earth is a mess of terrible acting, confusing plot points, and awful special effects.
Why It’s So Bad
From the over-the-top performances to the ridiculous costumes (John Travolta’s dreadlocks, anyone?), Battlefield Earth is a prime example of how not to make a sci-fi movie. The story is convoluted and filled with plot holes, the dialogue is cringey, and the CGI looks like it was created on a Commodore 64. It’s no wonder the movie won seven Razzie Awards, including Worst Picture of the Decade.
9. Plan 9 from Outer Space
Overview
Often called “the worst movie ever made,” Plan 9 from Outer Space is a 1959 sci-fi/horror film directed by Ed Wood. The movie revolves around aliens who come to Earth to resurrect the dead as part of their “Plan 9.” With its abysmal production values, nonsensical plot, and wooden acting, Plan 9 has become a cult classic for all the wrong reasons.
Why It’s So Bad
Where do we even begin? The cardboard sets, the visible boom mics, the stock footage that doesn’t match the rest of the movie… Plan 9 is a masterclass in bad filmmaking. Bela Lugosi, who was supposed to star in the film, died before production began, so Ed Wood hired a chiropractor to play Lugosi’s role. The result is a hilarious display of bad acting and even worse filmmaking.
8. The Room
Overview
While not strictly a sci-fi movie, The Room has become infamous for its awfulness. Written, directed, produced by, and starring Tommy Wiseau, this 2003 film is a confusing mess of a drama about a love triangle gone wrong. With its terrible acting, bizarre plot, and laughable dialogue, The Room has gained a cult following as one of the worst movies ever made.
Why It’s So Bad
The Room is a perfect storm of bad writing, bad acting, and bad directing. Tommy Wiseau’s performance is particularly cringeworthy, with his odd mannerisms and terrible line delivery. The plot is filled with bizarre subplots that go nowhere, and the dialogue is often nonsensical. Despite (or perhaps because of) its awfulness, The Room has become a midnight movie sensation.
7. Catwoman
Overview
Starring Halle Berry, Catwoman is a 2004 superhero movie loosely based on the DC Comics character. The film follows Patience Phillips, a shy artist who gains cat-like abilities and becomes Catwoman after uncovering a conspiracy at a cosmetics company. With its terrible CGI, cringey dialogue, and nonsensical plot, Catwoman is a prime example of how not to make a superhero movie.
Why It’s So Bad
From the awful cat puns to the ridiculous costume (what’s with the shredded leather?), Catwoman is a mess from start to finish. Halle Berry’s performance is over-the-top and cartoonish, the action scenes are poorly choreographed, and the CGI is laughably bad. It’s no wonder the movie won four Razzie Awards, including Worst Picture and Worst Actress for Berry.
6. Howard the Duck
Overview
Based on the Marvel comic book series, Howard the Duck is a 1986 sci-fi comedy that follows the adventures of an anthropomorphic duck named Howard. After being transported from his home world to Earth, Howard teams up with a rock singer and a scientist to stop an evil alien creature. With its terrible special effects, awkward sexual innuendos, and bizarre plot, Howard the Duck is a notorious flop.
Why It’s So Bad
From the creepy duck costume to the nightmare-inducing stop-motion effects, Howard the Duck is a visual assault on the senses. The movie’s attempts at humor are cringeworthy, the sexual innuendos are uncomfortable, and the plot is a confusing mess. Despite being produced by George Lucas, Howard the Duck was a critical and commercial failure, and it’s not hard to see why.
5. The Adventures of Pluto Nash
Overview
Starring Eddie Murphy, The Adventures of Pluto Nash is a 2002 sci-fi comedy set in a futuristic lunar colony. Murphy plays the titular character, a nightclub owner who gets caught up in a plot to take over the moon. With its terrible special effects, unfunny jokes, and uninspired plot, The Adventures of Pluto Nash is a forgettable mess.
Why It’s So Bad
Despite its talented cast and big budget, The Adventures of Pluto Nash is a prime example of how not to make a sci-fi comedy. The special effects look cheap and dated, the jokes fall flat, and the plot is a confusing jumble of sci-fi clichés. It’s no wonder the movie was a box office bomb, grossing only $7 million against a budget of $100 million.
4. Santa Claus Conquers the Martians
Overview
As the title suggests, Santa Claus Conquers the Martians is a bizarre 1964 sci-fi comedy about Santa Claus being kidnapped by Martians. The Martians, concerned that their children are becoming too attached to Earth television, decide to bring Santa to Mars to spread Christmas cheer. With its awful special effects, terrible acting, and utterly nonsensical plot, Santa Claus Conquers the Martians is a campy disaster.
Why It’s So Bad
From the cheap-looking Martian costumes to the cringeworthy attempts at humor, Santa Claus Conquers the Martians is a perfect storm of bad filmmaking. The plot is baffling, the acting is wooden, and the special effects are laughably bad. Despite its awfulness (or perhaps because of it), the movie has gained a cult following as one of the worst Christmas movies ever made.
3. Manos: The Hands of Fate
Overview
Often called one of the worst movies ever made, Manos: The Hands of Fate is a 1966 horror film about a family who stumbles upon a cult in the desert. With its terrible acting, incoherent plot, and mind-numbingly boring pacing, Manos is a test of endurance for even the most dedicated bad movie fan.
Why It’s So Bad
From the opening credits (which drag on for nearly ten minutes) to the abrupt ending, Manos is a chore to sit through. The acting is atrocious, the dialogue is stilted and repetitive, and the plot is a confusing mess. The movie’s low budget is apparent in every frame, from the cheap-looking sets to the shoddy lighting. It’s no wonder Manos has become a cult classic for its awfulness.
2. Troll 2
Overview
Despite its title, Troll 2 has nothing to do with the 1986 movie Troll. Instead, this 1990 horror film is about a family who vacation in a small town populated by goblins who want to turn them into plants. With its terrible acting, nonsensical plot, and atrocious special effects, Troll 2 has become a cult classic for its sheer awfulness.
Why It’s So Bad
From the cringeworthy acting to the laughable special effects, Troll 2 is a disaster from start to finish. The plot is filled with bizarre twists and turns that make no sense, the dialogue is stilted and awkward, and the goblins look like they were created by a kindergarten class. Despite its awfulness, Troll 2 has gained a dedicated following for its unintentional hilarity.
1. The Creeping Terror
Overview
Topping our list of the worst sci-fi movies ever made is The Creeping Terror, a 1964 horror film about a giant, slug-like alien that terrorizes a small town. With its terrible special effects, awful acting, and mind-numbing pacing, The Creeping Terror is a test of endurance for even the most dedicated bad movie fan.
Why It’s So Bad
From the opening credits (which feature a narrator droning on for nearly 10 minutes) to the abrupt ending, The Creeping Terror is a chore to sit through. The monster is clearly just a bunch of people crawling under a rug, the acting is wooden and lifeless, and the pacing is slower than molasses. It’s no wonder The Creeping Terror has become a cult classic for its sheer awfulness.
